Answer 1

Explicação passo-a-passo:

a) x = 37 - 12 = 25

b) x = 21 + 8 = 29

c) x = -60 - 13 = -73

d) x = -15 + 9 = -6

e) x  = -3 - 20 = -23

f) x = 30 - 9 = -21

g) x = 200/2 = 100

h) x = -333/3 = -111

i) 5x = 65. x = 13

j) 6x = 54, x = 54/6 = 9

k) 9x = 99, x = 99/9 = 11

l) 4x = 64 - 20 = 44, x = 44/4 = 11

m) 7x = 14 + 49 = 63, x = 63/7 = 9

n) 8x = 80 - 24 = 56, x = 56/8 = 7
